/edit: did a firmware upgrade of the AP and can’t replicate it anymore. Thanks all for the input, much appreciated. In case it happens again I will use your tips.
I have a very weird issue. I’ve got a relatively simple network setup:
- router connected to ONT (Fibre)
- 10 port switch A connected to router, cables to various places in house
- 4 port switch B connected to switch A, with TV & Xbox connected
- Unify WiFi AP connected to switch A, both 2.4Ghz and 5Ghz networks
That works well. However, when I connect the WiFi AP to switch B I’m having issues. Initially it all works well, but after ~30 minutes the wifi stops working; I can no longer ping e.g. the router. It only happens to one of the WiFi networks (2.4Ghz or 5Ghz), not both. A reboot of the AP solves it again, but then it stops working after ~30 minutes.
Both switch A and B are 1Ghz switches, zero issues with other devices.
Any idea what I can try?
from your router can you ping the AP behind that switch, while the issue is occurring? All L2 unmanaged switches, no tagging? POE from the switch or an injector? If from the switch maybe put an injector in between?
I work for an ISP in the network engineering dept, I personally have never seen an issue exactly like this before, but we generally do power calculations for switching and wifi, this sounds like a power issue to me.
I’ve just moved it back to behind switch B, will do testing as you suggest.
The switch doesn’t have POE, the Unifi AP does use POE via its own POE injector.
